Vidu Q1 Start and End Frames generates dynamic videos from a starting frame and an ending frame, incorporating creative storytelling and animation effects.
This is an asynchronous API and will only return the task_id of the asynchronous task. You should use this task_id to request the Get Task Result API to retrieve the video generation result.

Request Body

​
images
string[]
required
Two images: the first is the starting frame, and the second is the ending frame.Notes:
  1. Supports public URLs or Base64 format
  2. Aspect ratio must be close: the ratio between the starting frame and ending frame must be between 0.8 and 1.25
  3. Supported formats: png, jpeg, jpg, webp
  4. Maximum size: 50MB
  5. The length after base64 decoding must be less than 10MB and must include the appropriate content type string. For example:

string
Prompt description, up to 1500 characters.
​
duration
integer
Video duration (seconds). Defaults to 5 seconds. Currently, only the 5-second option is supported.
​
seed

Random seed for video generation.
  • Defaults to a random seed value
  • Manually set values will override the default random seed
​
resolution
string
Output video resolution. Defaults to 1080p. Currently, only the 1080p option is supported.
​
movement_amplitude
string
The range of motion of objects in the frame. Default value: auto
Optional values: auto, small, medium, large
​
bgm
boolean
Whether to add background music to the generated video. Default value: false
Optional values: true, falseWhen set to true, the system will automatically add suitable BGM. There is no duration limit for the BGM; the system will adapt it automatically.
